RemoteNtpTimeEstimator needed user to give a remote SSRC and it intended to call RtpRtcp module to obtain RTT, to be able to calculate Ntp time. When RTT cannot be directly obtained from the RtpRtcp module with the specified SSRC, RemoteNtpTimeEstimator would fail. This change allows RemoteNtpTimeEstimator to calculate NTP with an external RTT estimate. An immediate benefit is that capture_start_ntp_time_ms_ can be obtained in a Google hangout call.
